Emasculatome



Patented Aug. 5, 1930 LoYD v. HAsTINGs, or' iiiiesnn, Iowa;

Application ined January 21, iao. v'seriali N. nasse;

This invention is an attachment for an i emasculatome which is an instrument especially employed in castrating animals. Instead of the usual` cutting operation, involving the removal of the testicles, the instrument acts to pinch the seminal cord or duct, after which the scrotum or` gland simply dries up, and there is no wound.

In the use of such instruments it has been found that the help ofa second person is required, to prevent the duct or cord or parts from slipping out from between the jaws of the instrument at the ends thereof. The object of the present invention is to provide an attachment forsuch an instrument which will close or obstruct the space between the jaws, at one `side or end thereof, which prevents the cord or tissue from slipping out at that end, the other end however being left unobstructed so that the extra skin or parts can escape the Vpressure of the jaws of the instrument and thereby prevent injury theret0.

The inventionv will be understood from the accompanying drawing in which Figure l is a side elevation of the instrument with the attachment applied. Figure 2 is an enlarged side View of the jaws. Figure 3 is a section on the line 3 3 of Figure 2. Figure 4 is a detail in section of the attachment.

The main parts of the instrument comprise the pivoted jaws 6,`oper`ated by handles 7 pivoted to the jaws at 8 and vto each other atl 9 to form a toggle by means'of which appropriate pinching` pressure may be applied. The lips 10 of the jaws are rather wide and extend at right angles to the axis of the instrument. These parts are known heretofore.

The attachment invented bv me comprises a plunger 11 which ismounted to slide in a tube 12 fixed by a bracket 13 to one of the jaws 6, adjacent one end of its lip 10. The plunger is so positioned that when the jaws are closed it will contact with a boss 14 on the lip of the other jaw. The tube 12 has a slot 15 offset at one end as indicated at 16, and the plunger l1 is provided with a pin 17 which slides in the slot. This plunger is pressed from behind by a spring `18 coiled around a stem 19 projecting rearwardly from the pl-nngergand'- `has bearing through the` `ujpper end of the tube where it is provided with a ring orhandle 20 by-means of which the plunger can be retracted if desired, so as to be put out of operation, and when retracted i it may be turned to engage the pin 17 in the notch 16 and so hold it retracted. The formation incident to the ring 20 coacts with the adjacent end of the tube to limit movement Q0 of the plunger 11 in one direction under the influence of the spring 18.

Normally the plunger 11 is advanced,and in the usefof the tool the neck of the scrotumis seized between the lips of the jaws, .65 with the cord or duct preferably adjacent that end of the lips having the plunger 11 which', as the jaws are closed, contacts .with` the boss 14 and so closes the opening at that end between the lips, the cord being thus prekI0 vented from escapingr the pinch. The opposite end of the lips remain open with a space sufficient to permit the surplus skin and tissue to escape from between the lios if necessary. By the means described theoperation is simplied and can be performed 4by lone man, without-the diiiculties heretofore met due to slipping of the cord from between the jaws. As stated, the 'plunger can be retracted and fastened or held back by the slot and 8o v pin device, when it is not needed. It will be understood that as the aws are closed to applythe pinching pressure the plunger 11 is free to yield against the tension of the spring 18 to permit the lips to complete the pinch- 8b' ing operation.

Modifications may be made `within the scope of the following claims andfno limitation in this respect is implied.

I claim:

1. An attachment for an emasculatome or similar instrument, comprising pivotally connected jaws, the cooperating edges of which extend at right angles to the axis of the ini strument and a spring. pressed member LJ mounted at one side of one of the jaws of the Vinstrument in position to contact with the other jaw when the jaws are closed.

2., An attachment as in claim 1, said member comprising a sliding plunger. r if 3. An attachment for an emasculatome or similar instrument, comprising pivotally connected jaws, the cooperating edges of which extend at right angles to the axis of the instrument, a tube mounted on one jaw of the instrument, a plunger slidable in Vsaid tube, with its outer end inposition to contact With the other jawofthe instrument, and la spr-ing behind the plunger.

1 4. An attachment as in claim 3, vand means to hold the plunger retracted' when' desired.

5. An attachment as in claim 3, the *tube having a slot offset at its inner end andthe plunger having a pin projecting into vtheslot y and engageable in the offset to hold the plunger retracted v l j In testimony whereof I hereunto Vafli'x my signature.
